8.1.7.11 Module 11: Measurement value processing

Description

The integration depth parameter is used to specify the number of raw position data which is
used for integration in order to determine the position value.

In order to obtain positive or negative position values depending on the direction of move-
ment of the BPS 34, the count direction can be selected as normal or inverted in the output
data of this module.

In order to obtain more exact measurement data while in the static state or for very slow
travel speeds, the integration depth can be increased here. If, however, a high integration
depth is used for high speeds, the contouring error is increased. With respect to contouring
error and exact measurement data, very good results have been obtained using
8 integration steps. Using 8 integration steps, the integration time is 16 ms. Thus, the
BPS 34 delivers a new position value to the interface every 2 ms which is 8 ms old.
